Relating the Temperature to the Interference-Fringe Spectrum for a Long Chain of Bose Condensates

摘要

Interference of a chain of Bose condensates qualitatively depends on the relation between the condensate phases. If the phases are equal, the Talbot effect is observed. Even a small randomness in the relative phases alters the density spectrum: Peaks appears at momenta that are unusual for the Talbot effect. Here this alteration of the spectrum is simulated within a simple model. Also the relation between the temperature and the density spectrum of the interference fringes is described.
